I have added to my tableView
with navigationController
a bar button with text "Start!".
But I can not see it anymore in the storyboard.
In my build I can see it:
I think this is also the reason for this error log message:
pushViewController:animated: called on while an existing transition or presentation is occurring; the navigation stack will not be updated.
What can I do to make the bar button visible again?
The tableviewcontroller is covering the navbar in your storyboard. Check the properties in the storyboard and verify that your tableviewcontroller is inheriting his geometry. (setting is called inferred)
